The concept of hierarchical structures

A closer view of these hierarchical structures resulted in the definition of a series of rules governing these important structures [52]. These rules provide a guideline to understanding the complex cooperation of different structures and substructures. 

A multiphase structure in polymer systems is not unusual. This is only true for polymer blends but also for pure polymers where microphase demixing in copolymers is a well known effect and where glassy regions are observed together with crystalline phases. The glassy

Only a few studies have concentrated on the phase transitions in blends containing EP and PLCs. Zachmann and coworkers [68], for example, have published experimental results from blends of a poly (ethylene naphthalene-2,6-dicarbonate) and a copolymer with PHB. Their paper again proves the complexity of these types of blends and the validity of the concept of hierarchical structures.
